I'm the trustedcoin admin. 

From examining our logs it does not appear there is (or has been recently) any problem with our API since other transactions are being processed fine. 

The advice nerioseole gave is spot on.  Jiro, If you are still having problems, feel free to contact me directly via https://api.trustedcoin.com/#/contact-us  ... if you do so please indicate either the email address you used when you signed up or provide one of the bitcoin addresses in your account so that I can find your account.
